Landslide Performance Test System – Release 24.3 September 2024

RANAP Tab

The IuPS tab is used to define the radio and transport layers of the Iu-PS interface between the RNC and a 3G-SGSN SUT. The settings for the appropriate protocols are displayed based on your Protocol selection.

The IuCS tab is used to define the radio and transport layers of the Iu-CS interface between the RNC and MSC. The settings for the appropriate protocols are displayed based on your Protocol selection.

NOTE:

  • When Iu-PS and Iu-CS are both enabled (In MME Nodal and MME Node ) when Handoff Protocol = UMTS (IuCS & IuPS over IP) the Tcl variables will begin with luCs for the lu-Cs interface. The Iu-PS interface will use the regular Ranap Tcl variables.
  • When Iu-PS and Iu-CS are both enabled (In HNB GW Nodal ) when 3G Macro RNC Emulation is enabled, Tcl variables will begin with luCs for the lu-Cs interface and IuPs for the Iu-PS interface.

 

When you select the Mobility or Session Loading With Mobility test activity, a Mobility IuPS tab is added to the test case to define the interface for the handoff RNC.

Radio Access Network Application Part (RANAP) settings provide RNC link management and Radio Access Bearer (RAB) management for MNs, including RAB mobility management and signal integrity.

In HNB testing, the Iuh tab is used to define the radio and transport layers of the Iuh interface between the HNB and a HGW SUT. The settings for the appropriate protocols are displayed based on your UMTS Version selection.

In HNB testing, the Iu-PS tab is used to define the radio and transport layers of the Iu-PS interface between the RNC and a SGSN SUT. The settings for the appropriate protocols are displayed based on your UMTS Version selection.

n HNB testing, the Iu-CS tab is used to define the radio and transport layers of the Iu-CS interface between the RNC and a MSC SUT. The settings for the appropriate protocols are displayed based on your UMTS Version selection.

The RANAP settings, during HNB testing, provide Radio Access Bearer (RAB) management, RAN information management and location reporting for MS.

Location and Routing Information

You can configure the test to assign the same Location Area Code (LAC) and Routing Area Code(RAC) to every MN or define a range of values that will be evenly distributed among the MNs. These values are used in both the RANAP and GMM layers.

During HNB testing, the HNB Location Information appears on the HNBAP tab, and is sent from the HNB to HNB-GW to provide information on the location of the HNB.

Enter the same value in the Start and End field to use that value for every MN. Enter the lowest value in the Start field and the highest value in the End field to define a range of values. When you define a range of LAC values, RAC values, or both, the value is incremented for each MN. Example:Example:

Assuming the following settings:

Number of MNs: 5

LAC range: 0— 2

RAC range: 0— 1

The MNs will be assigned LAC/RAC combinations in a round-robin manner:

MN 1: 0/0

MN 2: 1/1

MN 3: 2/0

MN 4: 0/1

MN 5: 1/0

NOTE: In UMTS testing, ensure that the LAC range defined on the Mobility IuPS tab does not overlap the range on the IuPS tab. Handoffs must be performed between different LAC/RAC combinations.

Range: 0 — 65,535

Default: 0

Tcl Parameter:

RanapLac_1

RanapLacEnd_1

RAN Information Management (RIM)

When you test with Release 6, you can include the RAN Information Send procedure in the test. RIM messages are sent, at the interval you define, to an RNC in another test case via the SGSN. The SGSN is responsible for routing the message to the correct RNC based on the destination ID, MCC, and MNC contained in the message.

 

Use the RIM Messages Sent checkbox to enable the procedure and define the timing and destination of the messages with the following parameters:

Tcl Parameter: RanapIncRim_1

Range: 1 second or greater

Default: 1

Tcl Parameter: RanapRimTimeout_1

Apply Parameter Values from Test Data Files (RANAP)

See Test Data Files for further explanation and sample files. If a sample is not found for the specific TDF, you can obtain a sample file from your Technical Support representative. You may also use the following options to select an existing TDF or create/edit TDF-CSV files (TDF-CSV Editor). 

For most TDF Parameters used for Applying Parameters, each row in the file is the overridden value for a different “Session”, aka a different UE. But some TDFs are done in other dimensions, like Bearers, eNodeBs, Subscribers (2 per UE sometimes) or even Hosts, etc. Tooltips on the TDF Parameter: 

Note that the “ID” is a unique ID. Please Provide the ID when reporting issues with a TDF. For TDFs that do not apply / override Parameters, but instead are just their own configuration or data or media files you won’t see TDF ID row details.

TIP: When including large files, please be aware of memory limitations, since the TDF Editor shares memory with the Client.

NOTE: The available TDF options vary. on the L3-7 | IPSec tab > IKE with RSA Settings you may only select the Certificate TDF from TAS (these are non-CSV TDFs).

In addition, where applicable, any rules for defining TDFs are included in specific Test Cases. (For example, In MME Node test case, see MME Node - Provisioning TDF.)

From the DMF Window, press Shift+Alt+A to display the  Save DMF as Tcl window. Click the Save to File button to save as Tcl file. See additional details on Using the Tcl API.

 

Select/Create a new TDF-CSV

Allows you to create a new TDF by entering a file name that doesn’t already exist or select an existing file by entering a file name that already exists.

Click to open the Select Existing or Create window.

  • Navigate to the relevant library/folder,

  • Enter the name of the file:

  • If the file name already exists, the file is selected and applied in the test case.

  • If the file name does not exist, a message displays that says you are creating a new TDF and the embedded TDF-CSV will be launched.

    • Click Yes to launch the TDF-CSV Editor and create/save the new TDF-CSV.

    • Click No to select a different file

NOTE: If you do not have permission to save in the selected library, an error displays when you try to create a new file.
TIP: You may also navigate to the relevant library/folder and select file, and click OK.

 

Upload a New TDF to TAS

Click to import a new TDF file from your local folder and select in the test Case (instead of having to go to TDF Admin).

  • Navigate to the file on your local folder and select.
  • Then navigate to the location (library) where you want to save it on the TAS. You may rename the file, if required.  

View Edit Selected TDF in TDF-CSV Editor

Available only when you have selected a TDF on TAS. Click to open the selected file in TDF-CSV Editor (in place, that is, within the Test Case).

Edit the file and save. You may also click Save As to save the edited TDF-CSV to a different library and also rename the file, if required.

NOTE: You may also select a TDF from a library to which you do not have write permissions, edit the file as required, and save (Save As) only to a different library with the same file name or a different name.

The only options available are Save As and Cancel.

Open Selected TDF in Standalone TDF-CSV Editor

Available only when you have selected a TDF on TAS. Select to retrieve the CSV file and open it in the stand alone TDF-CSV Editor.

Generate Stub TDF-CSV

TIP: Available only when a CSV specification has been defined for in the Test Case for the TDF widget ( View TDF Actions/Options Menu)

 

Opens an example context specific test data parametersexample context specific test data parameters, which you may save as a .CSV file or open in the TDF-CSV Editor.

 

Launch Standalone TDF-CSV Editor

Click to open a blank TDF-CSV Editor.

The Launch Standalone TDF-CSV editor options handles very large TDFs that may use too much Client memory if opened within the Test Case/in the embedded editor.  You may set the standalone TDF-CSV Editor memory high to edit large TDFs.

Tcl Parameter: RanapCfgFileEn_1

NOTES:

  • RANAP file settings include UMTS Version.
  • Settings that can be changed on a handoff begin with "Mobility."
